Discover the submarine!?

Halsey, who had just breathed a sigh of relief, was almost shocked when he heard the bad news. .

It was a coincidence that these submarines came. He had just sent most of the destroyers at hand to stop the pursuers, and the German submarine came. Needless to say, the ones that came must be the new German submarine that was so fast that it could not be caught.

The fires on the three Iahua-class battleships have not been extinguished yet, and it is easy to see open fires on the dim sea.

The German submarines only need to aim at open flames to launch torpedoes, and they can sink three battleships that have suffered heavy losses.

"Anti-submarine!" Halsey already knew in his heart that there was a lot of danger, but he still refused to give up easily. "Iahua, Wisconsin, and Missouri immediately took the anti-submarine route, and the other ships carried out anti-submarine operations!"

Rumble...

Less than 5 minutes after Halsey's order was issued, the originally calm sea water began to boil like a pot of water, and several terrifying waves appeared on the sea in an instant.

This is the destroyer dropping a deep water bomb!

However, there is no German Type 21 U-boat under the sea where the deep-water bombs are dropped. This kind of submarine that can sail underwater at 17.2 knots is difficult to catch. Moreover, the number of American destroyers and light cruisers guarding around the three Iowa-class is limited, so they dare not abandon their protection and are seriously injured to catch the submarines.

So the deep water bomb that has been thrown down now is just a sound, arousing courage, and at the same time scaring the Nazi wolf pack in the sea.

"The Americans were frightened by us, they were throwing deep water bombs."

Lieutenant Colonel Erich Top, the captain of the u-3010 submarine and commander of the 27th Submarine Detachment, heard a dull roar, and saw the waves of fireworks rising from time to time from the periscope, and understood what was going on.

As a captain of a trumpet Uboat who had worked on a destroyer for a while and was no stranger to anti-submarine operations, he certainly knew what a weapon the Type 21 Uboat was that despaired the destroyer captain.

It is difficult for existing sonars to detect submarines underwater when destroyers sail at speeds of more than 18 knots, and the speed of Type 21 U-boats underwater is as high as 17.2 knots. If you want to track Type 21 U-boats, the destroyer must drive to more than 18 knots.

When the Type 21 U-boat sails at a low speed of about 5 knots, the submarine is quiet enough to avoid any existing sonar.

After successfully attacking destroyers (submarine attack destroyers!), the German U-boat captains mastered another useful trick. They first approached the enemy destroyers at high speed, deliberately made sounds, and then lowered their speed and drove quietly. The intimidated American destroyers are likely to throw deep-water bombs littered, and the explosion of deep-water bombs will make American sonar invalid in a short period of time. In this way, American destroyers will be completely unable to detect underwater U-boats. The 21 U-boat can naturally accelerate movement and look for opportunities to start easily.

At night just after September 5, 12 Type 21 U-boats led by Lieutenant Colonel Top adopted this tactic of scaring the Americans and successfully lured American destroyers to drop deep-water bombs.

Because of the interference of the deep-water bomb explosion on sonar (it takes 15 minutes for the deep-water bomb explosion to ignore its interference) now underwater has become the world of Type 21 U-boats. Even if they drive at full speed, the American destroyers cannot find it.

"Keep the depth and speed of 5 knots."

"The torpedo compartment is prepared, and use the T1 torpedo."

"Fight preparation."

Lieutenant Colonel Top, who had seen three Iowa-class battleships that were still emitting fire from the periscope, suppressed his excitement and issued one order after another. Six powerful t1 torpedoes were pushed into the six torpedo launch tubes at the bow of the boat.

It is different from the T2 torpedo with excellent occultism, but with a slightly slower speed (30 knots) and less than 200 kilograms of charge. The T1 torpedo, which uses traditional steam, has a larger speed and range. It can hit 6,000 meters away at a high speed of 44 knots and 8,000 meters away at a speed of 40 knots. Moreover, the T1 torpedo is also loaded enough. The warhead of the T1b type torpedo used on Lieutenant Colonel Top's submarine is equipped with a full 350 kilograms of high-performance explosives, which is theoretically enough to cause a heavy blow to the underwater protection of the Iahua-class battleship. The Iahua-class underwater protection can only resist the strike of 300 kilograms of Tienti explosives, and cannot stop the t1b torpedo with 350 kilograms of charge.

As for the shortcomings of the T1b torpedo, the tail of the torpedo during navigation is not a problem for the Type 21 submarine that can maneuver underwater at a high speed of 17.2 knots. Moreover, the sky is already very dark now, and if you want to see the torpedo tail, you have to turn on the searchlight, which will expose the location of the destroyer... The destroyer is also the prey of the Type 21 U-boat!

“6800 meters!”

“6500 meters!”

“6000 meters!”

“…”

Top's voice made the atmosphere inside the u-3010 boat become more and more tense, and drops of sweat kept dripping down everyone's foreheads and cheeks.

Everyone turned their attention to Lieutenant Colonel Top. At a distance of 6,000 meters, the t1b torpedo could reach a maximum speed of 44 knots. However, the order to launch the torpedo has not been issued for a long time.

Until Top reported the number "3000 meters", Lieutenant Colonel Top ordered in his deliberate voice: "No. 1, No. 2, No. 3, No. 4, No. 5, No. 6 torpedo prepared, set a 5-meter-degree depth. Start boosting!"

The current target is an Iowa-class battleship with a standard displacement of nearly 45,000 tons. Its underwater lightning protection armor cannot be weak. So Lieutenant Colonel Top is preparing to fire out 6 T1b torpedoes in one breath.

And to ensure the hit, he also took the risk of letting the submarine sail to a position less than 3,000 meters away from the target.

"Pressure is over!"

"Target 3000 meters, No. 1, No. 3 and No. 5 torpedo launches!"

"The number one, three and five torpedoes have been launched!"

"Torpedo launches in No. 2, No. 4, No. 6!"

"The number two, four and six torpedoes have been launched!"

The six bangs sounds were light, and the body of the u-3010 submarine was slightly shaken, giving people a feeling of briskness.

Six torpedoes sailed towards an Iahua-class battleship 3,000 meters away at a speed of 44 knots, and they would hit or miss it in about 2 minutes.

The u-3010 boat was silent, and everyone was waiting anxiously in their hearts. Time seemed to solidify at that moment. Lieutenant Colonel Top held his pocket watch and stared at the pointer. After the pointer had been around for more than two circles, his mood was extremely nervous.

Boom boom boom boom...

Three dull sounds came, and Lieutenant Colonel Top immediately raised his periscope and saw that the huge warship aimed at had been engulfed by the fire. The water wall that was falling was more than ten meters high in the fire!

Lieutenant Colonel Top stretched out his right hand and handed it over a Leica camera. Top put the camera lens on the eyepiece of the periscope to take a photo, then immediately took back the periscope and issued a loud order to evacuate: "Left rudder 20, evacuate at full speed!"

When the u-3010 boat was turning rapidly underwater and evacuated, Admiral Halsey, who was riding on the Little Rock light cruiser, suddenly felt his heart in his throat.

Three torpedoes hit the lightning-proof armor below the port waterline of the Wisconsin battleship. The huge destructive force formed by the 350 kilograms of Tienti explosives exploded underwater and immediately tore open the spliced ​​side main armor belt and main lightning-proof belt. However, the Iahua class has multiple watertight compartments and a three-layer ship bottom. In theory, the hits of 2-3 torpedoes cannot affect its combat effectiveness at all.

However, Wisconsin has been hit by four large missiles and has been seriously injured. The fire has been burning for several hours and has not been extinguished. Moreover, due to the violent explosion and fire, many of the equipment on Wisconsin has malfunctioned. It is hard to say whether it can withstand the strike of three German torpedoes.

Moreover... there should be more than one German submarine underwater, and it is impossible for them to launch only three torpedoes.

Halsey's conjecture quickly became a reality. Just a few minutes after the Wisconsin was hit by a torpedo, the 12 torpedoes launched by the U-3011 boats and the u-3012 boats, which also belonged to the 27th Submarine Detachment of the 1st Submarine Group, rushed towards Missouri and Iahua respectively. Seven of them hit the target, Missouri scored 4 torpedoes, and Iahua was hit by three torpedoes.

Less than 5 minutes later, the 27th Submarine Detachment's U-3013 and U-3014 both launched an attack, and 6 of the 12 T1b torpedo hit the target. Among them, Wisconsin hit the lightning again, occupying 4 of them, and 2 torpedoes hit a Fletcher-class destroyer that was throwing deep-water bombs next to Wisconsin while using searchlights to sweep across the sea (searching for the torpedo tail).

The attacks were then launched four 21 U-boats, including u-3015, u-3016, u-3017 and u-3018. These four U-boats fired 24 T1b torpedoes to three Yihua-class battleships that had fallen east and west on the sea! 13 of them hit the target!

In just less than 3 minutes, the other three submarines affiliated to the 27th Submarine Detachment, u-3019, u-3020 and u-3021, shot 18 torpedoes, and this time 10 torpedoes hit!
